I've tried a good handful of deep conditoners, both high end and drug store, and nothing seem to really do it for me. Either they were too moisturizing, or simply not enough. Then I tried the regular conditioner of this line, and fell in love with it, so I figured why not try this? Man. I wish I tried it sooner. I wasn't sure about it, since I'm not a fan of the leave in spray, but this sure is awesome. It super moisturizes my very dry hair, but doesn't weigh it down. It smells great, and I don't have to use a ton to cover my hair either. Great product, and would buy again!
